A Woodland man was arrested Saturday afternoon on suspicion of causing two vehicle crashes in Davis, killing one person and injuring another.

Armando Arias Gonzalez, 39, was being held Sunday at the Yolo County jail on two hit-and-run charges, and one count of vehicular manslaughter. His bond was set at $120,000.

Around 2 p.m. Saturday, Davis police responded to a report of a single vehicle crashing into a tree off of East Covell Boulevard, just east of Baywood Lane. The vehicle, a silver sedan, had a single occupant, an 85-year-old woman. She was transported to UC Medical Center, where she died.

The Sacramento County Coroner’s office identified the woman Sunday as Ruth D. Morales of Vacaville.

Shortly after the first crash, police received a second report of a two-vehicle crash at East Covell Boulevard and Pole Line Road. A Jeep that had been stopped at the light at the intersection was rear-ended by a Toyota Corolla.

“It (the Jeep) went into the intersection, and disabled the suspect’s vehicle (the Toyota Corolla),” said Sgt. Rod Rifredi with the traffic division of Davis police.

The driver of the Jeep - a woman who was not identified by police - had minor to moderate injuries, and was transported to Sutter Davis Hospital.

Police arrested Gonzalez, the driver of the Toyota Corolla, at the scene.

“We determined that the vehicle that caused that collision had caused the previous collision,” said Rifredi. “We have evidence at the first scene that the suspect made contact with that vehicle. “

Gonzalez suffered minor injuries and was taken by police to Sutter Davis Hospital.

Gonzalez is facing hit-and-run charges as he did not stop to render aid to the victim of the first crash, police said.

It was not known Sunday whether alcohol, drugs or speed were factors in the two crashes.

“We have a big mess that we have to go through,” said Rifredi.

He is asking for any witnesses to the two crashes to contact him at (530) 747-5413
